To (all ZUILDTI'I/ it nut concern/.-

Be it known that I,v CHARLES S. MAYNARD, a citizen of the United States, residing at Chardon, in the county of Geauga and State of )hio, have invented a certain new and useful Improvement in Temporary 'llelegraphs Stations, of which the lollowingisa full, clear, and exact description.

The objectoi the present invention is to provide an arrangen'ient for a temporary telegraph-stallon on a main line without permanent -onneetions therewith and without cut ing and splicing or otherwise injuring the line-wires.

The arrangement; is particularly applicable to those emergency cases arising l'rom wrecks or \vashouts aloi'ig railroads at points reinotel'romtlie stationsorsignal-tmrers; but it may, ol' course, be utilized wherever it is desired to temporarily connect instrumentsto the established lines.

It is essential in the event ol a Wreck or other accident along railroad For the l act to be reported to the lrain-rlespatcher and communication established with the general ollices as soon as possible, and the only method at present l'ollowed lor establishing such eommunication with the. permanent ollices is to have a lineman out one or" the telcgraph-wires and splice in z-oi'iucctions with the local "instrlmn-nt. Now this arrangement is dist inctly ohicctirmablc l'or many obvious reasons. in. the first place, it may be desired to establish a eonnrwtirm at a. point some distance lrom a. tel-egr:1pi:-poie where the lineman cannot cutthe main wire. .gai'r1,su h an arrangement rm iiires the pres-- enee on the ground ol' a lineman lo eui the wire and make the connections. the railroads and telegraph companies dislik very much. to cut their wires along the line (especially copper circuits} on account ol' permanent repairs, whi h must be made alter the temporarv eonnection is discontinued. 'ihcarrangenlent just recited, howu'er, is th only one heretol'orc known and ol' the wires leading l'rom the instrument hurt her,

vantages obvious to those familiar with such Work, not the least of which is the ability to establish communication almost the instant the operator is on the ground.

Referring to the accompanying drawings, Figure 1 is a diagram illustrating the condition of two main line-wires before the temporary station is established. Fig. 2 is a diagram illustrating the first step ol establishing the tempo ary station. Fig. 3 is a diagram illustrating the second step of establishing the temporary station. Fig. 4 is detail View of one end of the cross-connection by which to establish the temporary telegraphconnection, and. Fig. 5 is a modification of the form shown in Fig. 4.

Referring to "Fig. the two line-Wires A and A are parallel to each other along the line, but are not connected with each other, and consequently are absolutely independent. In the event that it is desired to establish tcanporai connection anywhere between the two permanent stations it is merely necessary to establish a cross 1) between these two wires, an instrument being located in the cross, ol" course. lhis cross may be, established in any number of Ways without cutting or in any other manner all'ecting the physical condition ol' the line-Wire. Prcl'crably, however. i. employ a line, spring-hook I), such as illusi ated in Fig l, which may be flattened, as shown in Fig. 5, to obtain greater contact-surface. i provide each one with one ol' those brass spring-hooks and place each of the hooks over a lirw-wirc, which may easily be done with a pole from the ground. As soon as this eross-eomicetion helween the two lin -wires is established the l'aet that there is a. cross somewherealong the line will he immediately indicated to the operators in the permanent stations I3 and C, as well as in the train-rlespatchens olliee, and the wire-Fidel will immediately proceed to locate th cross in the usual manner and inslruct the permammt olliee on one side of the the rail md: and telegraph companies have been loreed to put up with the attendant dis a-.l\'ant:i; s

i'vlff :ilon is ab olutely lree lion:

umh one ol 1 he has many ad novel arrangement lor a. temporery cross to leav one ol' the wires open and the permanent ollice on. thev other side ol the.

eross to leave the other wire open, and communication between the two pern'ianent stations will be established through the cross and through the temporary instrument in tho (JI'OSS.

tion is now established in a through circuit. This arrangement for a tern orary station merely involves temporarily throwing out of service one wire between the two stations -on either side of the temporary station, and when the temporary oflice is disestablished all that is necessary is to remove the-connections of the cross and no repairs of any kind will be required, as the physical condition of the line-wires will remain intact. It will be plain that this arrangement can be had at any point along the line, either at a pole or in between poles as it is merely necessary .to throw the hoo ed ends ofthe cross over the line-wires, which may be accomplished from the'ground.

providing the various telegraph-offices with the simple contrivanoe for making the connection, in case oi wrecks an o erator can be sent from the nearest ofiice an 001311111113111 cation established atthe scene of the wreck far in advance of the arrival of the Wmec'kingcrew.

It is obvious that the temporary star 1.. A temporary telegraph-station between two established stations comprising a crossconnection containing an instrument between two line-wires, one line-wire being open in one of said established stations, the

other lime-wine being open in the other of said 1 established stations. 7 f 2. The method of establishing connection or a two established stations consisting in making a temporary cross-connection containing instrument between two vline-wires and open-' orary telegraph-station betweening one line-wire in one of said established stations and the other line-wire inthe other of said established stations.

In testimony whereof I; hereunto affix my 5 signature in the presence of two witnesses.
